ICE-CREAM FREEZER.

To all whom it may concern Be it known that I, CHARLES H. EDDY, a citizen of the United States, residing at Attleboro, in the'county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Ice-Cream Freezers, of which the following is a specification. 1

This invention relates to ice-cream freezers and like devices, and has for one of its ob jects to provide a simply constructed device whereby a plurality of freezer devices may be simultaneously actuated and a corresponding variety of creams may be frozen at the same time and by one actuating mcchanism. V

Another object of the invention is to provide a device of this character of improved construction and increased eiiiciency.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the inven tion Figure 1 is a sectional side elevation of the improved device. Fig. 2 is a plan view with the parts in section on the line 22 of Fig. 1. Fig. 3 is a transverse sectional elevation. Figs. land 5 are enlarged perspective views of the holding brackets. Fig. 6 is an enlarged detached perspectiveview of a pair of the guide brackets.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device comprises in general an actuating mechanism supported upon a receptacle for the ice and forthe freezer.

cans, and arranged to simultaneously actuate a plurality ofthe cans, whereby a corresponding plurality of creams of varying flavors or qualities may be producedsimultaneously by one operating mechanism.

The tub or receptacle for the ice is represented conventionally at 10, and may be of any required shape or size and any required material, but if two of the freezer cans are employed the tub will preferably be elliptical as shown, but if a greater number of cans are employed thetub will preferably be circular. For the purpose of illustration a tub constructed of 'staves secured by hoops indicated at 11 is shown and provided with a bottom 12, these parts being of the usual Specification of Letters Patent.

construction. 12 of the tub are steps 13 to receive the lower journal 14: of thefreezer cans. Each of the freezer cans comprises abottom member 15 from which the stud 14 extends, 2. cylindrical intermediate member 16 and a cap or closure 17, the latter held in position by bayonet slots indicated at 18 in the cap 17 engaging over pins 19 extending from the upper. edge of the cylindrical member 16.

.The cans 16 and their attachments are precisely alike and the description of one will suffice for both. 7 I

Rising from the cap17 is a sleeve 20 terminating at its upper end in a pinion 21, the pinion sleeve and cap being preferably integral as shown. Mounted for rotation through each of the sleeves 20 and its pinion 21 is a vertical shaft 22 which extends downwardly through the can and is stepped at 23 in the upper face of the bottom 15 of the can; The shaft 22 is circular where it passes through the sleeve 21 and square or in other form than round where it passes through the interior .of the oan,as indicated at 24. S1idably engaging each square portionof each shaft is a frame comprising end members 25 and vertically connecting side members 26, the members 26 being knife-edged and disposed tangentially to'the interior of the can and to the shaft 22, as illustrated in Fig. 2. The members 252.6 being engaged upon the square portion 24 of the shaft are rotated by the shaft when the latter is revolved, as hereinafter explained. Directed outwardly from the connecting members 26 are small brackets27 to which arms 28 are plvotally united at 29.- The arms 28' ex,

tend toward theside walls ofthe can 16 and are formed with dependingsguide ribs 30 between which clearing blades .31 are supported. The arms 28 extend at their inner ends for engagement against the outer face of the. blade membersl26, as illustrated in Fig. 2. By. thismeansas the shaft 22 is rotatedthe frame: 25.-26 including its attachments will be rotated within the shell and the outer knife-edges of the blades 31 will scrape against the inner face of the can and being extended tangentially to the "can will turn thematerial toward the center, as willbe obvious.- The connecting members 26--being-likewise inclined tangentially relative to the can will likewise scrape the material toward the center. Directed inwardly from the connecting members 26 are agi- Patented Septt, 1915. 7 Application filed May 19, 1914. Serial No. 839,608.

Supported upon the bottom,

rection, but opposite to the cans.

.Mounted upon the upper outer face of the tub 10 at one side is 'a standard 33 having a transverse bearing rib or seat 34 and a socket 35, and likewise mounted upon the outer face of the tub or ice receptacle 10 at the opposite side is a similar standard 36 divided at the upper part to produce two vertical portions 37-38 spaced apart, and with a bearing seat or rib 39 extending across the divided portions and connecting them and'likewise forming a seat which is disposed in transverse alinement with the seat 34of the standard 33. Extending between the standards 33-36 and supported by the bearings 3439 is an upperplate or frame member 40 having a bearing-41 at one end: for engaging through the socket of I the'standard33 and reduced at the other end as represented-at- 42 to pass between the divided portions 3738' of the standard 36.

r A button or similar holding device 43 is pivoted upon one of the spaced portions of the bracket 36, .for instance the portions 37, and extends over the upper ends of the spaced portions and formed with a depending lip 44 at its free end and engaging over theouter face'of the spaced standard portion 38 to hold the adjacent end of the member 40 from upward movements By this arrangement the :member 40 is held from downward movement by the bearings 3439 and held from upward and lateral movement by the socket 35, the spaced members 37%38and thebutton 43, while at the same time the .member.4 0 and its attachments may be readily removed'by simply releasing the button-43 andlifting the member 40 upwardly.

porting frame comprising a lower horizontal portion 45 and verticalside portions 46 47, the member .45 :being secured in any suitablemannerto the side portions 4647. Extending laterally from the side portion 46 offthe lower frame is a lug 48, while a 'similar'lug 49 extends laterally from the portion47 of the lower .frame.:. Attached to .the inner face of the tub. 10 at opposite 1 sidesthereof are guide ribs 5051 between ifWlllCll the lugs 4849;'are supported, and

. prevented thereby from. lateralfldisplace ment. Theribs 50,51 and the lugs48-49 Depending from the member 40 is a supl thus coact with the standards 3l34 to from the tub and coupled thereto as required.

At their upper ends the shafts 22 are sup ported in bearings in the frame 40, and depending from the frame at its opposite ends are hoods 52-53. Stepped at 54 in the lower frame member 45 is a standard or support 55 having a transverse central bearing 56 to receive the inner end of a main drive shaft 57. The drive shaft extends between the spaced portions 37 38 of the bracket 36 and likewise through an open slot 58 in the receptacle 10, and is provided with an operating crank 59 at its outer end externally of the receptacle. Mounted for rotation upon the standard 55 at its upper end is a combined bevel and rim gear 60, while a similar combined bevel and rim gear 61 is mounted for rotation upon the lower end of the standard 55. A bevel pinion 62 is mounted upon the shaft 57 and engages the bevel portions of the gears -61. A pinion 63 is mounted upon each of the shafts 22 and engages with the rim portion of the gear 60, while the pinions 21 of the freezer cans engage with the rim portion of the gear 61. The pinions 63 are fixed upon the shafts 22 and rotated therewith, while the pinions 21 are loose upon the shafts. By this arrangement, it will be obvious, that when the shaft 57 is rotated by power applied to the crank 59 the pinion 62 will transmit the motion of the shaft continuously to the gears 60.61, in opposite directions and thence to the shafts 22 and the freezer cans, the shafts 22 and their attachments being rotated in the same direction while the freezer cans are rotated in the same direction but opposite to the rotation of the shafts. By this simple means, it will be obvious, that the freezer cans are simultaneously actuated in one direction, while the shafts 22 carrying the heaters will be rotated in the opposite direction, thereby applying a double motion to the compound to be frozen.

The improved device is simple in construction, can be strongly manufactured and by means of which two or more qualities or flavors of cream or like commodities may be frozen atjthe same time.

Having thus described the invention, what is claimed as new is:'

1. In a device of the class described, a resaid freezing cans and engaging one of said gear Wheels, a gear pinion connected to each of said beater devices and engaging the other gear Wheel, a shaft mounted for rotation in the transverse bearing of said standard, and a gear pinion carried by said shaft and engaging said gear Wheels, whereby the freezing cans and beater devices are rotated in opposite directions When motion is imparted to the shaft.
